SPRING CUSHION ooNsTmrcTIoN.

To all 'whom it may concern.'

Be it known that I, SAMUEL Sunxorr', a

.citizen of the United States of America',

and a resident of Chicago, Cook County,- Illinois,have invented' a'certain new and useful Improvement .in Spring Cushion Constructions, ofwhich the following is a specification.

Y This invention'relates to .improvements in spring cushion constructionand method of 'I manufacturing the same and' more especially toself-contained spring assemblies for upholstered seat cushions,furniture, mo-

tor cars and the like. f The object of the invention is to provide animproved method of fastening and sewing together the pieces of fabricthat'make' up the'outer coverin and inner compartmens or cells into.which the springs are in. sei-ted, the purpose being toprovide amplestrength, shaperetaining qualities, easel and rapidity in the sewingoperations, and ready insertion of the springs into the cover.

with a portion o A preferred embodiment of the invention is illustratedin the accompanying drawings, in which:

Figure 1 isa to plan view of a cushion i) the fabric removedf-t show theinternal structure,

Figure 2 1s an enlarged view 1n. vertical section taken longitudinallyor v`lengthwise .spring retaining member before sewed to the coverpieces.

A cushion of the type embodying the features of the invention consistsof. a casing of burlap fabric made up of pieces cut to size and' sewntogether on machines; Within this casing is a multitude of coil springsarranged in rows, each spring being separated from its neighbor bysurrounding walls of fabric, so arranged as to form individual 'cellsfor each spring. The ciishion may be of any shape, size and thickness,the one herein disclosed being square. l

Considering the cushion as a completed article of manufacture, the samecomprises a top cover piece 1 and a bottom cover piece "tances from sideto side,

2, the two being designated for the purpose "of this description only.These cover pieces are of equal size and square in shape, bein cut tolarger dimensions than the finishV cushion since the margins of each arefolded at right angles and their edges brought together and stitchedaround the sides and ends at 3, thereby forming the boxing or side walls4 and end walls 5.

. '1 he interior-of the cushion is divided into spring compartments .forthe individual springs 6. The Space is divided into longi-A tudinalcompartments extending the length of the cushion by' means of aplurality of I'partition walls -7, made of strips of burlap,

stitched along their ed esito the top and bottom pieces and exten ing'vertically or at right angles therebetween. These partition walls 7.are spaced a art at equal disdividing the space intov six (Figure 1) ofthese full length com artments.

Dividing each ot'` the lengthwise compartments into an equal number ofsmall Square compartments is a series of division walls 8, spaced apartat equal intervals and extending'transversely between the partitionwalls 7. The width of the division p walls 8 is less than the distancebetween the partition-walls 7 so that a space separates the edges of theformer from the latter, as clearly shown in Figure 3.

These division walls are not separate pieces but form a series of tabswhich are sewn to and form a part of a unitary. member, consisting of aplurality of such tabs i sewn to a long narrow strip 9, the, completemember being shown in Figure 5. This member, when in place, extendslengthwise between the partition walls 7, the lower ends of the divisionwalls or tabs bein stitched to the bottom piece 2, as shown in iiigures1 and 3, and the narrow conecting strip stitched to the to piece alonone edge only the lines of stitcliing being igndicated by `16 in Figpre1, and as it will be observed, ex-

tend parallelto and adjacent the lines of stitching 11, of the partitionwalls 7.' Thus it is seen that the division walls or tabs 8 arenot-sewed directly at both ends to the top and bottom pieces, but onlyat one end, the Opposite ends being sewn to the connecting strip 9,which in turn is stitched to the' top piece 1. In this ymanner one edgeof the connecting strip is 'free and partakes of the nature of a flap,the purpose of which will strip 9 is furthermore extended at its endsbeyond the length of the` cushion, in the form of end sections` 9", 9,which are carried down halfway of the end wall boxing and their extremeedges includedin the hem made by sewing the edges' of the to and bottompieces together at 3. This is c early shown in Figure 2. n l

10 Within these square compartments is inserted a spring 6, the. samebeing separated by the vertical-'wallson four sides. The method ofassembling the material to make the cushion involves aiseries of sewingoperations which must be carried out in a prescribed' order sinceotherwise-it would be impossible 'to usel 'sewing machines.

Hence, it is necessary to sew the free ends of the tabs 8 to the bottompiece as the first operation. Thus, beginning at one end of a bottompiece, 'all of the first or, end most row of tabs 8 ofthe severalconnected tab members, aresewn down by a single operation, then t-hesecond row, and so on until ,25 all are secured -to the same coverpiece.: Next, the partition walls are stitched down.

to the same piece and between the rowsof tabs 8, thereby completing onehalf of the' by sewing around the Ioutside along the line A 3, one endbeing left open` for the insertion of'the springs, this operation beingtermed loading.

. The loading of the cushion is carried out by means of a loadingfixture, lwhich in its 40 simplest formare two thin wood or metal stripsbetween which are compressed a row of springs of the number and spacingrequired to fill'a single row of cells within each' longitudinalcompartment. When compressed, the'strips are clamped together andinserted endwise into the open end of the compartment. In doing this,the fixture is inserted between the top piece l and the connecting stripor flap 9, so that it does not encounter the 'division walls or tabs 8.lVhen the fixture is inserted its full length, the same is twistedaxially toward and over the free edge of the flap, a halfeturn whichbrings each spring into its respective com-y partment with the vflapbeneath one end. By releasing the fixture, the springs expand and springinto their final positions, whereupon the fixture is withdrawn and thenext row loaded. When the loading is completed the open end is sewed up'andthe cushionjis complete.

The advantage of this particular construction, the rapidity and ease ofloading is greatly increased, in that the cushion can be completelysewed up for loading, and

connecting tabs Stitc then by the use of afixture the gang methodof'loading can be employed, which would be impossible were the edges ofthe .division tabs sewed. directly .to the top and bottom pieces, thusnecessitating the use of the space' at the corners of each cellfor-introducing a. spring therein, this being a slow tedious andexpensive operation.

Having set forth the important features of the cushion constructionembodying the invention, and explained the method of assembling andloading the cushion, I claim:

l. A method of constructing spring cushions consisting of providing aplurality of strips, each'having a series of ed transversely thereof,stitching the free ends of said' tabs to a cover piece in parallel rows,stitching one edge of each strip to another cover piece andsewingpartition strips vto said cover pieces and between the rows oftabs and connecting strips.v

l 2. A method of constructing spring'cushions consisting of providingastrip having a series of tabs stitched transversely thereof, stitchingthe free ends tof said tabs to a cover piece' in predetermined order andarrangement, sewing partition walls to said -cover piece, betweenthe'rows of tabs of each strip, providing another cover piece andstitching the free edge osaid partition strips and said tab connectingstrip to said last mentioned .cover piece.

3. A method of constructing springcush ions consisting of providingseparate cover pieces, providing aplurality of relatively narrowconnecting strips having a series of tabs sewed transversely thereof and'y at equal distances apart, sewing the free end of one of the endmosttabs of eachstrip in spaced relation along aline parallel to the endedge of one of said cover pieces, sewing the next series of tabs and soon until all are secured to the samecover piec, stitching a series ofpartition strips to said cover piece, andalong parallel lines betweensaid series -of tabs, applying another cover piece, and

securing one'edge of said connecting strip and the free edges of saidpartltion strips to.

said last' mentioned cover piece.

' 4. A method of constructing spring cushions consisting of providingseparate cover pieces, providing a plurality o f relatively narrowconnectingstrips having a series of tabs sewed transversely thereof andat equal distances apart, sewing the free e'nd of one of the endmosttabs of each strip in spaced relation. along a line parallel to the endedge of one of said cover pieces, sewing thenext series of tabs and soon until all are secured to the same cover piece, stitching a series ofpartition strips to said cover piece, and` along parallel lines betweensaid series of tabs, applying another cover piece, sewing onelongitudinal edge of said connecting strip and the free edges of saidpartition strips to said last mentioned cover piece, sewing the marginsof said cover pieces together around the sides and one end of thecushionto form the boxing, one end of said connecting strip being sewed withthe end margins-of the cover pieces, and loading the compartments formedby the partition strips,. rom the open end of the cushion by inserting aloaded fixture be- 10 tween the connecting strip and the adjacent coverpiece, rotating the xture to bring the springs into the individualspring compartments, and releasing the springs from the fixture.
